There are two kinds of research that you can cite in your paper. Primary research is something you do yourself, such as giving a survey, poll, questionnaire, doing an experiment, or interviewing someone. Secondary research is when someone else did the research for you, and you cite their work. Including research in your paper not only strengthens your argument but also provides more details (numbers!) to help your reader understand you.
Statistics is a great way to strengthen your supporting detail in a paragraph. This data can be gathered from both primary and secondary research. If you decide to do primary research and survey a large group of people, such as a class, how can you report your findings?
